Description

Technical Field

[0001] This utility model relates to the field of fastener technology, specifically to a fastener designed to prevent detachment. Background Technology

[0002] Fasteners are common mechanical parts used to connect, fix and control components. Anti-loosening fasteners are a type of fastener that, through special design or treatment, can effectively prevent the fastener from falling off the fixed component during use.

[0003] Existing fasteners are often secured by screws and nuts. Over time, the screws and nuts can loosen, affecting the stability of the connection between the bolts and components, and thus causing the bolts to fall off easily.

[0004] Therefore, we propose a fastener that can prevent loosening of the screw and nut, thus improving the fastening effect. Utility Model Content

[0005] The purpose of this invention is to provide a fastener that prevents detachment, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fastener for preventing detachment, comprising a first mounting bracket, a second mounting bracket disposed below the first mounting bracket, a screw being sleeved inside the first mounting bracket, a nut being sleeved on the outer wall of the screw, and a processing component disposed outside the screw, the processing component including an anti-detachment component disposed outside the screw, and a positioning component disposed above the anti-detachment component.

[0007] Preferably, the anti-detachment component includes a mounting hook fixedly installed inside the second mounting bracket. A retaining plate is sleeved on the outer wall of the mounting hook. A sliding rod is slidably arranged inside the retaining plate. A spring is sleeved on the outer wall of the sliding rod. A push block is fixedly installed at the end of the sliding rod. A first fixing ring is fixedly installed on the outer wall of the push block. A first locking block is fixedly installed on the top surface of the first fixing ring. A second fixing ring is fixedly installed at the bottom of the nut. A second locking block is fixedly installed on the side of the second fixing ring away from the nut.

[0008] Preferably, the positioning component includes a locking hole formed inside the first mounting bracket, a first magnetic block is fixedly installed on the inner wall of the locking hole, a locking rod is engaged inside the locking hole, and a second magnetic block is fixedly installed at the end of the locking rod.

[0009] Preferably, one end of the spring is fixedly installed on the side of the push block away from the first locking block, and the other end of the spring away from the push block is fixedly installed on the top surface of the locking plate. Under the elastic action of the spring, the first fixing ring can be pushed to stably engage the first locking block and the second locking block.

[0010] Preferably, the first and second locking blocks are distributed circumferentially around the center of the first and second fixing rings, and the outer walls of the first and second locking blocks are inclined. The locking and restraining of the first locking block on the side away from its inclined side and the second locking block on the side away from its inclined side is used to prevent the nut from falling off.

[0011] Preferably, the second magnetic block is magnetically attracted to the first magnetic block, and the outer wall of the second magnetic block is slidably disposed inside the card hole. Under the restriction of magnetic attraction, the screw is positioned and installed on the first mounting bracket.

[0012] Preferably, there are six clamping rods distributed around the center of the screw, which can be used to position and install the screw under the constraint of the clamping rods.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The anti-loosening fastener is composed of an anti-loosening component. When connecting the first mounting bracket and the second mounting bracket, the clamping plate is sleeved on the outer wall of the mounting hook, and the screw is sleeved through the first mounting bracket and the second mounting bracket. The nut is rotated so that it is sleeved with the screw. The second fixing ring and the second clamping block fixed at the bottom of the nut rotate accordingly. The second clamping block contacts and presses against the inclined surface of the first clamping block. As the nut rotates, it moves towards the first mounting bracket. Under the elastic action of the spring, it pushes the push block, causing the push block to drive the first fixing ring and the first clamping block to move towards the first mounting bracket. The first fixing ring and the second fixing ring press together, so that the side of the first clamping block away from its inclined surface engages with the side of the second clamping block away from its inclined surface, preventing the nut from reversing and falling off. This structure can prevent the nut from falling off under the restriction of the engagement of the first and second clamping blocks.

[0015] 2. The anti-loosening fastener is composed of a positioning component. When the first mounting bracket and the second mounting bracket need to be installed, the screw is sleeved through the first mounting bracket and the second mounting bracket, so that the locking rod fixed on the side wall of the screw engages with the locking hole opened on the inner side of the first mounting bracket. Under the magnetic attraction between the locking rod and the second magnetic block, the screw can be positioned inside the first mounting bracket and the second mounting bracket so that the nut can be sleeved with the screw. This structure can assist in the connection between the screw and the nut, and prevent the screw from sliding out of the first mounting bracket when the nut and the screw are sleeved.

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] Example 1: A preferred embodiment of the anti-loosening fastener provided by this utility model is as follows Figures 1 to 6 As shown: A fastener designed to prevent detachment, comprising a first mounting bracket 1;

[0025] A second mounting bracket 2 is provided below the first mounting bracket 1;

[0026] The first mounting bracket 1 is internally fitted with a screw 3;

[0027] A nut 5 is fitted onto the outer wall of the screw 3;

[0028] The machining component 4 is disposed outside the screw 3. The machining component 4 includes an anti-detachment component 41 disposed outside the screw 3. The anti-detachment component 41 includes a mounting hook 411 fixedly installed inside the second mounting bracket 2. A retaining plate 412 is sleeved on the outer wall of the mounting hook 411. A sliding rod 413 is slidably disposed inside the retaining plate 412. A spring 414 is sleeved on the outer wall of the sliding rod 413. A push block 415 is fixedly installed at the end of the sliding rod 413. A first fixing ring 416 is fixedly installed on the outer wall of the push block 415. A first locking block 417 is fixedly installed on the top surface of the first fixing ring 416. A second fixing ring 418 is fixedly installed at the bottom of the nut 5. A second locking block 419 is fixedly installed on the side of the second fixing ring 418 away from the nut 5.

[0029] In this embodiment, when the first mounting bracket 1 and the second mounting bracket 2 are connected, the clamping plate 412 is sleeved on the outer wall of the mounting hook 411, and the screw 3 is sleeved through the first mounting bracket 1 and the second mounting bracket 2. The nut 5 is rotated so that it is sleeved with the screw 3. The second fixing ring 418 and the second clamping block 419 fixedly installed at the bottom of the nut 5 rotate accordingly. The second clamping block 419 contacts and presses against the inclined surface of the first clamping block 417. As the nut 5 rotates, it moves towards the first mounting bracket 1. Under the elastic action of the spring 414, it pushes the push block 415, causing the push block 415 to drive the first fixing ring 416 and the first clamping block 417 to move towards the first mounting bracket 1. The first fixing ring 416 and the second fixing ring 418 press down, so that the side of the first clamping block 417 away from its inclined surface engages with the side of the second clamping block 419 away from its inclined surface, preventing the nut 5 from reversing and falling off. This structure can prevent the nut 5 from falling off under the restriction of the engagement of the first clamping block 417 and the second clamping block 419.

[0030] Furthermore, one end of the spring 414 is fixedly installed on the side of the push block 415 away from the first locking block 417, and the other end of the spring 414 away from the push block 415 is fixedly installed on the top surface of the locking plate 412. Under the elastic action of the spring 414, the first fixing ring 416 can be pushed, so that the first locking block 417 and the second locking block 419 are stably locked together.

[0031] Furthermore, the first locking block 417 and the second locking block 419 are distributed circumferentially around the center of the first fixing ring 416 and the second fixing ring 418. The outer walls of the first locking block 417 and the second locking block 419 are set with slopes. Under the locking and restriction of the side of the first locking block 417 away from its slope and the side of the second locking block 419 away from its slope, the nut 5 is prevented from falling off.

[0032] Example 2: Based on Example 1, a preferred embodiment of the anti-loosening fastener provided by this utility model is as follows: Figures 1 to 6 As shown: The positioning component 42 includes a locking hole 421 opened inside the first mounting bracket 1. A first magnetic block 422 is fixedly installed on the inner wall of the locking hole 421. A locking rod 423 is locked inside the locking hole 421. A second magnetic block 424 is fixedly installed at the end of the locking rod 423.

[0033] In this embodiment, when the first mounting bracket 1 and the second mounting bracket 2 need to be installed, the screw 3 is sleeved through the first mounting bracket 1 and the second mounting bracket 2, so that the locking rod 423 fixedly installed on the side wall of the screw 3 is engaged with the locking hole 421 opened on the inner side of the first mounting bracket 1. Under the magnetic attraction and restriction between the locking rod 423 and the second magnetic block 424, the screw 3 can be positioned inside the first mounting bracket 1 and the second mounting bracket 2 so that the nut 5 can be sleeved with the screw 3. This structure can assist in the connection between the screw 3 and the nut 5, and prevent the screw 3 from sliding out of the first mounting bracket 1 when the nut 5 is sleeved with the screw 3.

[0034] Furthermore, the second magnetic block 424 and the first magnetic block 422 are magnetically attracted to each other. The outer wall of the second magnetic block 424 is slidably disposed inside the card hole 421. Under the restriction of magnetic attraction, the screw 3 is positioned and installed on the first mounting bracket 1.

[0035] In addition, there are six clamps 423, which are distributed around the center of screw 3. Under the constraint of clamps 423, screw 3 can be positioned and installed.

[0036] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
